摘要:
The present invention includes a novel subtype of the P2-purinergic receptor, referred to as the P2Y12 receptor. This receptor is expressed selectively in the platelets and brain, and couples to a pertussis toxin-sensitive G protein (Gi). Nucleic acids encoding the receptor and associated screening and therapeutic methods are also disclosed.
摘要:
A novel subtype of the P.sub.2 -purinergic receptor, referred to as the P.sub.2U2 receptor, is disclosed. This receptor is activated by four of its agonists in the following order of specificity: UTP>UDP>ADP>ATP. Nucleic acids encoding the receptor and associated screening and therapeutic methods also are disclosed.

摘要:
The invention relates to novel compounds of formula (I) containing fused heterocyclic ring systems which are effective platelet ADP receptor inhibitors: In formula (I), W is carbon or nitrogen, wherein at least one W is a carbon; and Y is nitrogen, oxygen, or sulfur. Such compounds including pharmaceutically acceptable salts are useful in various pharmaceutical compositions for the prevention and/or treatment of cardiovascular disease particularly those related to thrombosis.
摘要:
The present invention relates antidotes to anticoagulants targeting factor Xa. The antidotes are factor X and factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. The derivatives describe herein lack or have reduced intrinsic coagulant activity. Disclosed herein are methods of reversing anticoagulation, stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.
摘要:
Methods of modulating platelet procoagulant response are taught herein. Inhibition of platelet procoagulant response with agents that inhibit the Ca2+-sensitive K+ channels, or Gardos channels, preferably while maintaining platelet bleeding arrest function, may be used to treat a variety of disorders.
摘要:
The invention provides methods and compositions for rapid and reversible inhibition of platelet aggregation in human subjects in need thereof by administering compounds of the formula: alone or in combination with a second agent which can be aspirin or a thrombolytic agent.
摘要:
A platelet substitute consisting of large unilamellar lipid vesicles that contain phosphatidylserine or another procoagulant (clot-promoting) phospholipid, a protein that has binding affinity for collagen or other component of the vessel wall that becomes exposed upon vessel injury, and/or a phospholipid scramblase, has been developed. This platelet substitute provides a means for selectively delivering procoagulant phospholipids and/or fatty acids to the site of vessel injury through targeted adherence to collagen or other component exposed upon vessel injury. These are particularly effective due to the combination of targeting procoagulant vesicles to a site of injury, and triggered exposure of phosphatidylserine (PS) on the surface.
摘要:
The present invention is directed to pharmaceutical compositions and methods of using combination therapies containing [4-(6-fluoro-7-methylamino-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl)-phenyl]-5-chloro-thiophen-2-yl-sulfonylurea, or a pharmaceutically acceptable salt thereof, for the treatment of thrombosis diseases.
